Bea knpwn that i, HENRY s. seem, Cai- Zen of the United States,residingat Mil e waukee, countyof Milwaukee, and State of`fliiscon'sirl, have invented new and useful Improvements in Pulpers, ofwhich the following is afspecification. c c

My `invention relates to improvements in 1 pulpers. ,y s e The object ofmy invention is to provide means Afor macerating" vegetable ber, such'as corn stocks and other material adapted fore'themanufacture of paperand other ary ticlesiny `which fibrous material is employed. It is wellknown that vegetable fibers are easily broken and destroyed whereordinary pulping.; mechanism is employed and the oblflt,` 0i, myinvention, more `specifically stated, is to provide meansforpulpingvegetablegr'owths yin `which the breakage and` de,-structioii,offtheiiber will bereduced to a mineurs, i inthe ,dieser.is`c n Figure 1` is a general elevationof my intical section.l ,v c e c, e

the plungerbwhen the ballsor weights en-` counter resistance, thesprings oteringim` creasing resistance to the upward movement. Saidsprings Garealso` adapted, by their recoil, to actuatethe pulping`ballsor weights downwardly with considerable violence after aperiodotspring compression, andatter the resistance has ceased, which causedsuch a compression. It "is therefore "bf vious that, when the plunger Fisrecipf,

weights I4" e intolmsuccessive hammering contacts with a` quantity ofvegetableber within the vat,eachof the balls will `be allowed t tostrike upon` the contents `o'tthe vat subl" stantially with ,hammerblows,the `force be-` ing substantially equal "to its own momen-.j tum,`since the springs, when distended, will` oiier but little resistancetothe upward movement of the ball.

,itwiu also @observed thawing te fact that the stems c f extend `looselylthrough` the plunger apertures, the balls,` orweights Fiwill bepermitted to swing from side to side or forwardly or backwardly, fwhereby theywillccllectivelyreach all portions of the `material withinthe vat, and whereby also they will be permitted,"whenl striking raisedbodies of material, toinovetoward onesideEthereof and again strike othermaterials at lowerlevels under` the recoil of the The l clutbhes M` areprovided with similar teeth fmJ and `aresupported `fromthe end of leverL by a pivotedhanger rod O, connected with a cross bar whichis attachedtothe extremity of the lever `atlA` spring e O- tends` to hold hangers`with;

The brackets R are secured to a frame bar R. The lever L is secured to aframe post L and its long arm is connected with the cross bar P, wherebyay stroke of considerable 'length may be imparted to the plunger F.

` I, do not limit the scope of my invention to ticularly the specificmeans forr actuating the plunger yis'not-essential, but I prefer toemploy means for lifting the plunger to .a predetermined height and thenallowing it to? drop by gravity, whereby substantially uniform blowswill be struck by the balls or weights F upon the material within thevat A.' Itfis` obvious that, ifgthe plunger were moved' `downwardly bymeans of the lever vat would "be struck would depend very largelyuponthe quantity of the material, or upon thelieight to which portionsOfthe material may extend, and it would be dithwould overcome thesevariances in the force ofl lthelblows imparted'to the materialsuficiently to avoid breaking the fiber `on one handor failing yto pulpit on the other hand.

I have also discovered that there vis a great advantage in allowing theplunger to drop bv gravity .owing to the fact that each of the weightsor balls acquires considerable momentum and a quick hammer blow isimparted to the material, which isL very 'effecoperation.'` I' thereforeProvide a repot' tive in causing a separation of the ber from theintervening' bodies of cellulose.

The contents of the vat are preferably heated,fpreparatory and duringthe pulping or burner S. Any suitable fuel may be employed to heat thecontentsof the vat.

5. Pulping mechanism including the combination with a vat, of avertically movable plunger therein, a set of weights loosely suspendedfrom the plunger, and adapted to move to a limited extent both laterallyand vertically with reference to the pliniger and to each other, andmeans for vertically reciprocating the plunger, said plungerreciprocating means including a vertically moving clutch adapted tointermittingly lift and release the plunger, whereby the latter ispermitted to drop after each lifting operation. y

6. Pulping mechanism, including the combination with a vat, a plungertherein provided with a toothed operating rod, a verticallyreciprocating clutch adapted, when depressed, to engage said rod and'meansforl releasing the clutch from the rodfwlyienyin4 its raisedposition, to allow they plunger to drop by gravity.

7 Pulping mechanism, including the coin-` bination with a vat, a plungertherein provided with a toothed operating rod, a verticallyreciprocating clutch adapted, when depressed, to engage said rod, andmeans for releasing the clutch from the rod when in its raised position,to allow the plunger to drop by gravity, saidplunger being provided witha set of loosely connected depending weights, eachladapted forindependent impact with the material when the plunger is dropped. n
